Title: Image stabilizing method for image forming device
Inventor: ARAI AKIO
IPC: G03G21/06
Filed: 1989-06-02
Abstract: PURPOSE:To surely stabilize an image even at the time of using a function separation type photosensitive body where the electric charge transporting function and the electric charge generating function are separated from each other by destaticizing the photosensitive body after electrifying it with the electrification polarity for normal image formation and the opposite polarity except at the time of normal image formation. CONSTITUTION:Except at the time of normal image formation, a photosensitive body 5 is destaticized after being electrified with the electrification polarity for normal image formation and the opposite polarity. That is, only a transfer charger 17 is discharged to electrify the surface of the photosensitive drum 5 with the positive polarity, and the transfer charger 17 is turned off and discharging is performed, and then, the surface potential is gradually reduced. Thereafter, the surface of the photosensitive drum 5 is electrified with the negative polarity by a temporary charger 13 to remove the remaining electric charge of the positive polarity, and the temporary charger 13 is turned off, and the surface of the photosensitive drum 5 is exposed by an electrification preprocessing exposure lamp 20 to remove all of the electric charge on the surface. Thus, the image is surely stabilized though the function separation type photosensitive body where the electric charge carrying function and the electric charge generating function are separated from each other.

Title: Alkaline battery
Inventor: IZUMIKAWA TOSHIHIKO
IPC: H01M4/06
Filed: 1982-08-10
Abstract: PURPOSE:To improve the liquid-leakage resistance of an alkaline battery by using a positive mixture the upper periphery of which has the same height as the stage part of a positive case and which is provided with a concave part in the center of its upper surface, and using a negative mixture which is provided with a concave part with which said concave part is filled through separating member. CONSTITUTION:A positive mixture prepared by mixing 10pts.wt. mercury oxide used as an active material and 5pts.wt. graphite, after being packed into a positive case 1, is adjusted to have the same height as a stage 2 and provided with a concave part in the center of its upper surface. Next, the positive mixture is unifiedly molded in such a manner that its upper peripheral part and central concave part are smoothly continuous with each other. After that, a negative mixture prepared by kneaking zinc powder used as a negative active material with a gel-like alkaline electrolyte, is packed into an assembly sealing plate, which is made by attaching an insulating gasket 8 consisting of a polyamide resin to the periphery of a sealing plate 7 which is formed by the use of a nickel-iron-copper three-layered clad member, in such a manner that a convex part with which the concave part provided on the upper surface of the positive mixture is filled is formed. Owing to such constitution as above, the upper periphery of the positive mixture can completely support the insulating gasket 8 and the sealing plate 7. As a result, there is no possibility that the insulating ring or the sealing plate sinks during sealing, thereby enabling the liquid leakage resistance.

Abstract: PURPOSE:To reduce an error due to the play of a driving mechanism, to correct the distortion of an image due to the inclination of an optical member in one direction, and to obtain an image which has small variance by providing a means which stops an optical member closely to a set position from one side at all times and positions the optical member. CONSTITUTION:When set magnifications are inputted at a magnification setting part 72, they are inputted to a controller 62 to calculate position information on the set position 72. Position information (a) on the current position 87a of the optical member 82a is inputted from a position detection body 86b to the controller 62. Those pieces of position information (n) and (a) are compared with each other to detect the optical member 82a being on one side 88a when YES or on the other side 88b when NO. A moving mechanism 81 puts the detection body 86b close to the set position 87 from one side 88a under the control of the controller 62 and stops the body. Consequently, the distortion of the image is made invariably constant and the variance is reduced greatly.

When the coach passes through the AC-AC section (a) reaches a point of a distance l3, the main circuit switch 15 is closed again. Accordingly, a motorman requires no special operation on passing through the AC-AC section.

Filed: 1986-06-17
Abstract: PURPOSE:To obtain a uniform oxide film by a method composed of steps of mounting a silicon substrate in a vessel, filling rare gas in the vessel, exhausting the gas, setting oxygen inputting amount to the vessel and heating the substrate. CONSTITUTION:This method contains steps of mounting a silicon substrate or a substrate formed with a silicon film in a vessel having a heater and to be exhausted, filling rare gas in the vessel, introducing oxygen gas into the vessel, so setting oxygen inputting amount to the vessel so as to hold the oxygen gas pressure in the vessel in desired pressure lower than the atmospheric pres sure, and heating the substrate at 800 deg.C or higher by a heater. The interior in a vacuum vessel is replaced by the rare gas, such as argon gas, the vessel is then evacuated in vacuum, and exhausted by a vacuum pump while introduc ing oxygen thereto to hold a desired pressure reducing state, heated by a heater to thermally oxidize at a low speed. Thus, a uniform oxide film is obtained.

Title: Preventive system for unneeded wave of impatt-diode injection synchronous amplifier
Inventor: IMAI TOSHIO
IPC: H03F3/10
Filed: 1977-11-22
Abstract: PURPOSE:To prevent the generation of unneeded waves and the sudden variaftion  in output level, by controlling the bias current of an IMPATT diode corresponding  to the magnitude of an input signal. CONSTITUTION:When input signal level Vin decreases, the output of inversional amplifier 7 appears and control transistor Tr8 starts operating. As a result, since the collector potential of Tr8 decreases by the current composed of the collector current of Tr8 flowing to resistor 14 and the base current of Tr9, the base voltage of Tr9 decreases to cause a current flowing to the IMPATT diode to decrease and, in consequence, the self-excitation oscillation output of IMPATT oscillator 1 also decreases. Therefore, when Vin becomes below a certain value, the bias current of oscillator 1 decreases and the ascillation output is decreased. Charaeteristics of Vin  of oscillator 1 to the bias current and output level are shown in reference to control  unneeded part (alpha) of the bias current with small Vin, part (beta) where the bias  current is controlled corresponding to Vin, and saturation part (gamma).
